Description

[Detailed description of the invention] This invention relates to an aluminum fence, which is constructed by attaching upper and lower horizontal bars to multiple posts via joint blocks, and the constituent members are interchangeable. , was created with the aim of providing an aluminum fence that allows the fence to be continuous in the left and right direction, has high assembly strength, is easy to assemble, and has good workability during assembly. .

Hereinafter, an explanation will be given with reference to the drawings showing an embodiment of the present invention. Reference numeral 1 indicates a column, 2 indicates a horizontal bar, and 3 indicates a small vertical bar, all of which are manufactured by extrusion molding of aluminum. .

The column 1 has a horizontal beam end contact surface 11 and a horizontal beam end side contact surface 1.
2, substantially U-shaped horizontal beam end fitting portions 4 are formed symmetrically along the longitudinal direction and on the left and right side surfaces of the support column 1.
Multiple pieces can be provided.

The end surface of the horizontal beam connecting joint block 5 is brought into contact with the horizontal beam end surface abutment surface 11 of the support column 1, and fixed with fixing tools 6 such as rivets or screws.

Both ends of the horizontal beam 2 are externally fitted to the joint block 5, and the end face and end side surface of the horizontal beam 2 are connected to the horizontal beam end surface abutting surface 11 and the horizontal beam end side surface abutting surface 12 of the support 1. The joint blocks 5 and both ends of the horizontal beams 2 are connected by fixing devices 7 such as rivets or screws, and the horizontal beams 2 are constructed between the supports 1.

In this embodiment, the vertical bar 3 attached to the horizontal bar 2 is
An example is shown in which a piece with the same length as the vertical spacing is attached between the horizontal bars 2, but there is also a case where a vertical small bar that is longer than the horizontal bar spacing is attached.

An embodiment of the present invention is as described above, but the specific shape and structure of the fence constituent members such as posts, horizontal bars, vertical bars, joint blocks, the material of the joint blocks, and the fence Various changes can be made to the mutual relationships of the structural members without departing from the gist of the present invention.

As described above, in the present invention, a substantially U-shaped horizontal beam end fitting portion consisting of a horizontal beam end surface abutting surface and a horizontal beam end side surface abutting surface is attached to the support along the longitudinal direction and on the left and right sides. The end face and end side surface of the horizontal bar are in contact with the horizontal bar end face contact surface and the horizontal bar end side contact surface of the support, respectively, and the support and the horizontal bar are In addition, since the support column and the horizontal beam are in planar contact after assembly, a strong connection can be obtained, and there is sufficient stress against forces in the front-rear direction and the up-down direction.

In addition, the approximately U-shaped horizontal beam end insertion portions are formed on the posts along the longitudinal direction and symmetrically on the left and right sides, so during construction, the fence can be configured with the left and right posts or three or more posts. The same support can be used as an intermediate support in the case where the fence is used, making it compatible, making it possible to manufacture fence constituent members economically, and facilitating inventory management.

In addition, the fence according to the present invention not only eliminates the need for welding, which is required for conventional steel fences, but also allows joint blocks to be used as guides when connecting the horizontal beams and posts. It has various practical effects such as easy assembly because it is connected by a tool.

Claims (1)

[Scope of utility model registration request] In an aluminum fence in which upper and lower horizontal bars are attached to a plurality of posts via joint blocks, the posts have a substantially U-shaped structure consisting of a contact surface on the end surface of the horizontal bars and a contact surface on the side surface of the end of the horizontal bars. The horizontal beam end fitting portions are formed symmetrically along the longitudinal direction and on the left and right side surfaces, and the end of the horizontal beam connecting joint block is brought into contact with the contact surface of the horizontal beam end surface of the support. The ends of the horizontal bars are fitted onto the joint block, and the end faces and side surfaces of the horizontal bars are connected to the contact surfaces of the horizontal bar ends and the side surfaces of the horizontal bars of the columns. This aluminum fence is characterized in that the joint blocks and the ends of the horizontal beams are connected by fixing devices.
